I CONTAIN MULTITUDES: THE MICROBES WITHIN US and a GRANDER VIEW of LIFE (audiobook) by Ed Yong



Published by HarperAudio in 2016.
Read by Charlie Anson.
Duration: 9 hours, 52 minutes.
Unabridged.

Ed Yong takes his readers (or, in my case, listener) into the tiny world of microbes. Traditionally, we think of microbes as tiny invaders that make us sick and, as I sit at home after yet another day of social distancing, it is easy to see it that way.

But, Yong takes us into a more complicated world. A world where microbes actually benefit their larger hosts - where microbes can help produce scents or colors for attracting a mate, help guts break down leaves or nuts and even help their hosts survive poisons. In many cases, these microbes and their hosts co-evolved and have become dependent on one another. They have created their own microbiome.

But, it's not that simple, either. Sometimes the microbes affect their host's behavior - and not in a good way. They can turn insects into virtual zombies, they can make mice hyperactive or depressed. They can even make mice suicidal (there is a microbe that resides in the guts of cats. It makes mice confuse the smell of cat with the smell of a mouse that is ready to mate. The mouse runs to the cat, gets eaten and the microbe is happily deposited in the gut of a cat. )

Yong's real message is that there are no good microbes or bad microbes. There are microbes that are good in some places and horrible in others. Your gut microbes, for example, are usually great, but if you have a leak in your gut, those microbes can kill you - and do it in a hurry.

Yong does explore relatively new ideas, such as the idea that gut microbes can change mental attitude, weight, cravings for certain types of food and more. It is true, but it is also true that it is certainly not as easy as it sounds. Some combinations of microbes work with some people with some foods in some situations. All of these combinations make it tricky.

Also, those probiotic yogurts that are so popular do nothing to help. It's not because they aren't helpful, but that you would have to eat A LOT of yogurt and keep doing it to actually change your gut biome.

I was intrigued by a discussion of the traditional concept of infection and how to avoid it. Turns out, if you use a medicine or a cleaner that kills all microbes, it can allow infection because the proper microbes aren't present to crowd out (or even kill) the microbes we consider dangerous. Also, if you want to build a strong immune system in your kids - get a dog.

This book was full of interesting information. At times, it was tremendously interesting. But, at two different times in the book, I seriously considered quitting the book. It has a slow start and a big lull about a third of the way through. For that reason, I am rating this audibook 4 stars out of 5. It can be found on Amazon.com here: I CONTAIN MULTITUDES: THE MICROBES WITHIN US and a GRANDER VIEW of LIFE (audiobook) by Ed Yong.

THE BALLOT and the BIBLE: HOW SCRIPTURE HAS BEEN USED and ABUSED in AMERICAN POLITICS and WHERE WE GO from HERE (audiobook) by Kaitlyn Schiess

Image
Published in 2023 by ChristianAudio.com. Read by the author, Kaitlyn Schiess. Duration: 6 hours, 27 minutes. Unabridged. I first heard about Kaitlyn Schiess on one of my favorite podcasts: The Holy Post . She is one of the three regular hosts of the show and often serves as their in-house theologian. She is well-suited for this role because she offers well-considered answers and she thinks them through before she answers, rather than just shooting her mouth off - all the more impressive when one considers that she is by far the youngest member of the podcast. I was drawn to The Ballot and the Bible because: 1) I am concerned the rise of Christian Nationalism in America and the damage it does to the Christian witness; 2) I knew that Schiess would give thoughtful answers. The intermingling of Christianity and politics is not a new phenomenon in the United States (or in the rest of the world - but that is not the focus of this book.) Schiess looks at the intermingling of faith and politi

ILLEGAL (graphic novel) Written by Eoin Colfer and Andrew Donkin. Illustrated by Giovanni Rigano.

Image
  Published in 2018 by Sourcebooks Young Readers. Illegal is the fictional story of two young brothers from Ghana: Ebo and Kwame. While it is fictional, it is based on lots and lots of true stories. Most Americans are very aware that immigrants/refugees are fleeing from their native countries and arriving at the border of the United States and are not aware that a similar thing is happening in Europe.  Europe has a similar refugee/immigrant situation. People are fleeing from the wars in Syria, Sudan, and Yemen. There are also refugees fleeing the brutal poverty and political situations in sub-Saharan Africa. Like in the United States, these immigrants/refugees depend on very shady people to move them closer to their goals. In this story, two young brothers named Ebo and Kwame live in a village in Ghana. They are orphaned and living with a useless, drunken uncle. They have an older sister that has already crossed the Sahara Desert and the Mediterranean Sea to look for work but they don

BENITO MUSSOLINI: A LIFE from BEGINNING to END (World War 2 Biographies) (kindle) by Hourly History

Image
  Published by Hourly History in 2017. Mussolini and Hitler in 1937. Nowadays, Benito Mussolini is best known as Hitler's far lesser partner in the Pact of Steel (signed in 1939), the formal treaty of the Axis Powers. He is often seen as the weaker partner that may very well have drug the entire alliance down due to incompetence.  But, back when Mussolini took power in Italy in 1922, he was seen, by some, as the vanguard of the future of political organization in Europe - a movement called fascism . He was at least begrudgingly admired by people all around the world.  This is, perhaps, the most balanced of all of the Hourly History biographies. I was mostly interested in a brief look at how Mussolini came to power and what he did once in power. The biography was a little skimpy on Mussolini's years in power before World War II and it won't please students of the war to see how little they discuss of his wartime policies and decisions. That being said, I thought this was a p

INCREDIBLE HULK: PLANET HULK written by Greg Pak, illustrated by Carlo Pagulayan, Aaron Lopresti, Juan Santacruz, Gary Frank, and Takeshi Miyazawa.

Image
Originally published by Marvel Comics from 199-2007. Synopsis: Hulk is banished from Earth after helping The Avengers, The Fantastic Four, and others defeat a common enemy by using Hulk's brute strength. Hulk has been rendered unconscious and placed on a spaceship.

Sakaar is ruled by a despotic, deranged emperor. He rules a planet with multiple species - all of them hate each other because he pits them against them against one another. He has discs attached to their bodies to control their impulses and allow him to deliver pain at will. He wears a suit of armor that Iron Man would envy and he r

DIFFER WE MUST: HOW LINCOLN SUCCEEDED in a DIVIDED AMERICA (audiobook) by Steve Inskeep

Image
Published by Penguin Audio in 2023. Read by the author, Steve Inskeep. Duration: 8 hours, 57 minutes. Unabridged. It's been said that no American has been the subject of more biographies than Abraham Lincoln. I don't know if that it is true, but I do know that it is pretty tough to come up with a new angle on the 16th President. In Differ We Must , NPR reporter/host Steve Inskeep has managed to do just that. Inskeep follows through Lincoln's life and sees how he dealt with people that he had disagreements with. Some of them were major, some were minor. Sometimes, Lincoln responded to these disagreements by befriending the people he disagreed with, sometimes by patiently arguing his point of view, sometimes by appearing to accommodate them only to slowly change their minds, and sometimes by arguing fiercely against his opponent. And, sometimes, as in the case of Frederick Douglass, Lincoln realized he was wrong and changed his mind as  was the case with Frederick Douglass (a

THE JOURNEY in BETWEEN: THRU-HIKING EL CAMINO de SANTIAGO (Thru-Hiking Adventures book 1) (kindle) by Keith Foskett

Image
E-book Published by Amazon Digital Services in 2010. I have a real soft spot for books about travel - especially travel in odd ways. I have read a book about a guy who backpacked across Europe, a man who hiked across Afghanistan in 2002, a man who biked from England to India, two women who biked from Turkey to China, a man who hiked from Mexico to the Darien Gap in Panama, the same man hiked the length of the Nile River, a man who found a little dog while in a hiking competition in the Gobi Desert, a man who hiked all 48 mountains in New Hampshire with his little schnauzer dog, and more. One of these travel stories was by this author, Keith Foskett. Last year, I read the story of his trip up the Pacific Crest Trail  - from Mexico to Canada and almost all in the mountains. This hike was much more sedate and featured less extremes in the weather. The Camino de Santiago is a well-established route. It has been an pilgrimage route for more than 1,000 years and in the last 30 years or so F

Appaloosa DVD

Image
A western for grown-ups. It's not about the guns, horses or bullets. It's about friendship, sex and, ultimately, love. Movie released in theaters in 2008. Be warned right now - this movie review is mostly one giant spoiler. Here's the non-spoiler parts right up front. This is a movie that strives to look authentic. The two main characters have known each other for years and have no need for a lot of dialogue - they know each other well, they know each other's habits and their conversations are spare. Many reviewers have missed the whole point of Appaloosa . It was not about two buddies/lawmen bringing peace to a town, although that does happen (mostly) and the gun fights are quick, brutal and ugly. The movie is about what happens when such a partnership is disrupted by a woman. Look at the DVD cover art and you can see it symbolically represented - there is Renee Zellweger standing between Mortensen and Harris. ****Spoiler alert****The rest of the review is jus

YEARS THAT CHANGED HISTORY: 1215 (The Great Courses)(audiobook) by Dorsey Armstrong

Image
Published in 2019 by The Great Courses. Lectures by Dorsey Armstrong. Duration: 12 hours, 29 minutes. Unabridged. The Great Courses offers a lecture series by college professors that the average person can listen to on their own time.  In this case, Purdue University history professor Dorsey Armstrong is focusing on the year 1215 as a pivotal year.  1215 is well-known to Americans as the year of the Magna Carta, but it is also the year of the Fourth Lateran Council of the Catholic Church. The rest of the lecture series is about general things that were going on around 1215. These include the crusades, a brief look at the Americas, a look at the Islamic world, Japan, and an extended look at Genghis Khan and the Mongol Empire. This is a lecture series that could have used a bit of editing. If two hours were removed, that would have been good. Three hours would have been great. This was especially true in the section about Genghis Khan. Armstrong admitted that she was excited about this

RESOLUTION (Virgil Cole and Everett Hitch #2) (audiobook) by Robert B. Parker

Image
Published by Random House Audio in 2008 Read by Titus Welliver Duration: 4 hours, 40 minutes Unabridged At the end of Appaloosa, the first book in this series, Hitch and Cole have parted ways. Hitch ends up in the town of Resolution, a mining/lumbering town with some small unsuccessful ranches/farms scattered around. Hitch is hired by the owner of a local hotel/saloon to keep the peace inside the saloon. Soon enough, Cole shows up. He is on the outs with his girlfriend again. She has issues - she just has to throw herself at the most powerful man in the room and Cole had finally had enough of it and killed a man she was with. For Cole, this is devastating. He has always followed the law, even if it is arbitrary law that he has written himself. Killing this man broke the law and Cole is now a man who cannot follow his own code. So, Cole just hangs out with Hitch and ponders the meaning of laws and rules and the Social Contract for half of the book. In the meantime, Hitch is
